M3.2 Earthquake 49 km ESE of Plush, Oregon — March 16, 2023
2023-03-16 20:33:40 UTC (2023-03-16) · approx. 12:33 PM UTC-8 local
On March 16, 2023 at 20:33 UTC, a magnitude 3.2 shallow crustal earthquake struck 49 km ESE of Plush, Oregon, at a depth of 8.3 km and coordinates 42.1883°, -119.3873°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 858 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 93 m — a useful intuition for the size of the slip patch on the fault.
